So I'm doing the King of the Dwarves quest and I was at the part were you enter the cavern where Colonel Grenda is stationed at the entrance. He tells you to speak with Veldaban, as well as your quest log, but I cannot find Veldaban anymore. He was previously following me, but now I cannot find him, and I even checked all over Keldagrim in case I accidentally did something which caused him to stop following me. I even tried just continuing the quest and talking to Colonel Grimsson but all he says is something along the lines of "you don't have any business here." In short, where can I find Veldaban?
